SAW HANDLE Filed June 30, 1936 5 Sheets-Sheet 3 gmc/WDM Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to saws, and more particularly has reference to an improved handle therefor.

The present invention is an improvement over the saw handles shown in my patents, No.

2,015,373, issued September 24, 1934; No. 2,038,- 819, issued April 28, 1936, and my application Serial No. 774, led January 7, 1935.

One of the objects of my invention is to provide a saw handle which is light, sturdy and easy to manufacture.

Another object of my invention is to provide a saw handle which may be readily attached to saw blades of various kinds and produced by various manufacturers.

Yet another object of my invention is to provide a saw handle having a covering of a hard rubber like material.

Still another object of my invention is to pro- Vide a saw handle which carries an oil reservoir in the handle.

A further object of my invention is to provide a saw handle having a strengthening beading extending around the edge of that portion of the handle which carries the saw blade.

A still further object of my invention is to provide a saw handle which carries an oil duct in the beading extending around the edge of the blade engaging portion.

Yet a further object of my invention is the provision of a hollow saw handle which carries a suitable measuring device therein.

Another object of my invention is to provide a saw handle having a novel lubricant channel which is integral with the handle.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention may be varied in construction, proportions and arrangement, without departing from the spirit and Scope of the appended claim.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect without limiting the improvements in their useful applications to the particular constructions which, for the purpose of explanation,

have been made the subject of illustration.

Briefly, this invention embraces a saw handle composed of two metal halves which are pressed into the desired configuration. The pressed halves are then secured together by spot welding 35 or some other suitable electrical process. The assembled handle comprises a hollow hand engaging portion and a blade engaging portion. I prefer that the hand engaging portion serve as a reservoir for a suitable lubricant. In lieu of the 40 above structure, the hollow handle may carry a suitable tape measuring device.

Extending from the grip portion of the handle and around the edge of the blade engaging portion is a strengthening beading. This beading not only improves the appearance of the handle but also serves to carry the lubricant from the reservoir in the hollow handle to the saw blade.

Moreover, the blade engaging portion of the 50 handle is so constructed that it can be attached to saw blades of various types produced by various manufacturers.

The saw handle is covered with a hard rubber like material. Not only does this improve the appearance of the handle but it also affords a better gripping surface for the hand of the user. This coating will also serve to prevent any damage to the saw handle. Furthermore, a hard rubber coating is particularly desirable in that it does not react easily to physical and chemical conditions such as heat and cold.

While I have specifically pointed out the use of hard rubber as a coating, it is of course to be understood that other plastic materials may be employed; for example, Bakelite, a condensation product of the phenols and formaldehyde, is another highly eicient coating. A number of other synthetic resins also may be used.

Referring to the drawings, in which like numerals designate similar parts, and more particularly to Figure 1, there is depicted a saw blade I provided with a handle 2. The handle is made up of two metallic halves which are pressed into the desired shape. As best depicted in Figure 7, it can be seen that the two halves are attached together by spot welding or some other suitable process in order to present the completed handle. A

The handle is then covered with a hard rubber like material 3. The rubber compound may be of any suitable composition. It will be appreciated that the rubber coating greatly improves the appearance of the handle and also aiorcls a better grip member.

The handle is composed of a grip portion 4 and a blade engaging portion 5. In Figure 2 it can be seen that the blade engaging portion is provided with a slot 6 for receiving a saw blade I.

The grip portion 4 of the handle 2 is hollow and is used as a reservoir for a suitable lubricant. The reservoir is designated l', as shown in Figure 3. A metal sleeve 8 is tted into the upper portion of the hand grip iorserving as an opening through which the lubricant can be admitted into-the reservoir. The inner periphery of the sleeve 8 is provided with screw threads which engagescrew threads on the stem of a closure cap member 9 which closes-the opening. The cap member 9 may be provided with a transverse slot IIJ for receiving a suitable instrument, such as a screw driver, for opening the aperture.

As best shown in Figures 6 and 7, a hollow beading or raised portion II extends from the lubricant reservoir 1 in the grip portion around the edge of the blade engaging portion 5. The beadingnot only strengthens the -blade engaging portion but also improves the appearance of the handle. A

The beading forms a depressed area I2 in the blade engaging portion 5. Within this area are' a plurality of apertures I3. There should be a relatively large number of these apertures which may be spaced to correspond with the apertures in the various types of saw blades with which the handle may be used.

As hereinbefore pointed out, the handle is covered with a coating of hard rubber or the like 3. Obviously when the coating is applied to the metallic halves it will ll the apertures I3 and afford a uniform appearance to the blade engaging portion of the handle.

V The rubber coating is so molded that the surface of the coating will be provided with indentations orthe like I3. The indentations indicate the location of the apertures I3 in the blade engaging portion. It will be appreciated from the foregoing that, when the operator of the handle desires to adapt it to a particular saw blade, all that is necessary to do is to knock out the portion I3 of the rubber coating opposite the aperture I3.

As is well known, saw blades are provided with apertures which` register with the holes in the blade engaging portion 5 and the securing means are then inserted through the aligned apertures for securing the blade and handle. While I have shown the use of two such apertures in the saw blade, it is to be understood that such number is merely illustrative, as the number of apertures will vary as the various manufacturers produce blades which have a different number of apertures, or apertures which are otherwise disposed.

After the blade I is tted within the slot 6 in the blade engaging portion so that its apertures will correspond with at least some of the apertures I3 in the handle, suitable securing means such as screws I4 are fitted therethrough in order to secure the handle and saw blade together.

As can be best seen in Figure 2, the beading II surrounding the depressed area I2 isrofV suiii'.- cient height so that the screws I4 are completely shielded from contact with an object which may engage the beading I0; that is, the screws are embedded in the area I2 out of harms way. This structure permits the ready removal of the blade, a quick adjustment to tighten the blade, and at the same time prevents the chance of any injury to the securing means by virtue of the depressed area in the blade engagingmember.

As hereinbefore pointed out, the beading or raised portion II is hollow. Referring to-Figs. 8 and 9, it can be seen that the beading is provided with a shoulder I6. It is believed to be apparent that the open portion of the beading can be closed by welding a metal strip I'I on the shoulder I6. I prefer that the closing strip be Welded on each half of the handle before they are assembled and thateach strip be ilush with the remaining portion of the blade engaging portion 5. be readily appreciated that the beading in each half of the handle can be employed as passageways for transmitting the lubricating oil from the reservoir in the grip portion in order toimpinge it upon each face of the saw blade I.

The blade engaging portion 5 is provided with a channel member I8 Which extends perpendicular to the beading I I. The closing strip ITI has a cut away portion I9 in order that the member I8 will be in constant communication with the interior of the beading II. It is believed to be apparent that when the saw is being used for a sawing operation, the lubricant from the reservoir 6 will flow through the beading I I by gravity,

out through the opening I9 in the closing strip,

into the channel I8 and thence upon the saw blade.

In Figure 9 there is shown a modified form of lubricating passageway for supplyingV the oil to the saw blade. In this form,it can be seen that the beading itself forms the channel which communicates with the blade. The remainder of the beading is closed by a second closing strip 20. In this form, instead of employing the beading itself as the passageway, a small piece of tubing 2| runs from the reservoir through the beading for carrying the lubricating oil. The discharge end of the tubing 2I is tapered as at 22, providing a restricted discharge aperture.

From the foregoing description it will be appreciated that I have provided a handle for a saw in which a lubricant reservoir is carried in the hand engaging portion. Moreover, the channel for carrying the lubricant from the reservoir to the blade is integral Withv the handle. In addi- It will Y tion to serving as a channel it also greatly strengthens the blade engaging portion and does not detract from the appearance of the handle.

In Figure 10 there is shown a saw handle which is constructed in the same manner as the handle depicted in Figure 1. In this form, however, the hollow grip portion 4, instead of serving as a lubricant reservoir, carries a conventional tape measure 23. The tape 24 extends through an aperture 25 in the top portion of the hand grip 4 and is provided with a tab 26. This tab not only permits the grasping by the user of the tape but also prevents the complete retraction of the tape through the slot into thegrip member.

As heretofore pointed out, the tape measure is of conventional construction and is preferably of that type which is operated by a spring pressed button 21. As shown in Figure 11, the button 21 extends through the grip portion of the handle and into a recessed portion 28.

It is believed that the advantages of the foregoing structure are readily apparent. The operator of the saw is enabled to have both a saw and a suitable measuring device in a single unit with the advantages that such a saw affords. The tape measure is so mounted in the grip portion of the saw that it does not interfere with the sawing operation and is at the same time ready for immediate and convenient use.

In Figure 13 I have shown another form of measuring device which may be used. The handle is cut away in order that a suitable casing member 29 may be inserted therein. It should be noted that the top portion 30 of the casing is of substantially the same configuration as the top portion of the grip member 4.

The casing is of such size as to conveniently hold the tape measure 3 I, as shown in Figure 15.

The tape 32 is provided with a tab 33 for facilitating grasping by the operator.

The case 29 is pivoted in the grip portion of the handle 4 by means of a pin 34. The forward end of the top portion 30 is provided with detents 35 which are adapted to engage the depressed areas 36 in the handle portion 2. It will be appreciated that the above structure will tend to keep the casing within the grip portion of the handle. By grasping the front end of the portion 30 the casing 29 will be moved about its pivot 34 so that the tape measure may be employed.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claim.

I claim.

A saw handle formed in two substantially mirror-image halves, each of said halves comprising a grip portion and a blade engaging portion, said blade engaging portion being offset from the line of juncture of said halves a distance half the width of a saw blade, said grip portion having a part bellied out from the line of juncture and adapted to form a lubricant reservoir with the other of said halves, said half having a concave groove on the juncture side joining said bellied-out portion and extending from it around the edge of the blade engaging portion, said groove having sunken shoulders, a sealing strip fitting on to said shoulders in counter-sunk relationship with the surface of said half on its juncture side, said blade engaging portion having at its lower side a second concave groove intersecting the rst mentioned concave groove and adapted to t along the edge of a saw blade, said sealing strip having a cut away portion adjacent the second mentioned groove.
